Children with bad breath that is caused by digestive problems can be treated by rubbing acupoints such as the middle and lower epigastric points. If a child’s bad breath is caused by indigestion, rubbing the middle and lower epigastric points can help relieve bad breath by dredging the liver and nourishing the stomach, eliminating food stagnation (promoting food digestion), and harmonizing the stomach and spleen. The middle epigastric point is located in the upper abdomen, 4 inches above the middle of the umbilicus, on the front center line; the lower epigastric point is located in the upper abdomen, 2 inches above the middle of the umbilicus, on the front center line. There are more causes of bad breath in children, such as tooth decay and periodontitis, so it is important to clarify the cause before taking treatment measures. It is recommended to teach children to brush their teeth properly in the morning and evening, and rinse their mouths after meals, which can reduce bacterial growth and effectively relieve bad breath. It is recommended to consult a doctor in time to clarify the cause of bad breath.
